I updated the FW to the 20200507 version on both the RD5R and the GD77.

My RD5R still has the offset issue. The pi-star doesn't even detect the signal. Its using the same codeplug as the GD77 which is doing fine.

s/n RD5R*A74**

s/n EU20161105** I am in the US and it looks like I got an EU version. Which was obvious when I looked at the ac adapter and the converter they included.

The GD77 can easily connect to the pi-star. BER is 0.1%

I will put the RD5R back in the box :) Once its working well it will be nice to have a smaller DMR radio to walk around with.

Thanks for all your work on the firmware updates!

Yep.

The RD-5R version still has a lot of bugs which need to be ironed out, before this version is ready for mainstream use.

Where can you find the FW version from 20200507?

On the Github's release page ;)

Cheers.

Can anyone using this radio please zip a backup of their calibation data and post it to this thread, saying whether their radio has the frequency offset problem or not, and which version of firmware they are running.

i.e was your radio on the correct frequency orginally, but my fix to move it by 1.5kHz caused problems, or vice versa etc

Thanks

Here is the backup of the calibration. I don't have a frequency meter, but I can only say that the radio works in hotspot mode up to 30/4 fw, has problems with 3/5, works very well (except the hotspot function) with 7/5

I don't have a frequency counter either.

I just used a SDR dongle to compare the frequency when transmitting with the official firmware and with the open firmware.

OK.

I think I know the problem.

The RD-5R is not using this calibration data because everyone's data is the same.

Please can you upload your Flash backup to your google drive, so I can compare it with my flash backup.

(You won't be able to attach it to the forum because the file is too large)

Here are the frequency data using a sdr dongle calibrated on local bridges: 145.000000 -> 145.000511
430.000000-> 430.001312
435.000000-> 435.001572

con fw originale:

145.000000->145.000140
430.000000->430.000114
435.000000->435.0000019

with the 30/4 fw (hotspot mode works) I have the same data as the 7/5 fw

and this is the link to google drive for radio backup
